With a true MD2 form factor, this adapter is ideal for low-profile
height and half-length adapter slots. Eight internal 6 Gb/s SAS
ports allow connection to 6Gb/s or 3Gb/s high-performance SAS
drives, high-capacity SATA drives or a combination of both.

Enhanced entry-level availability

The Intel RAID Controller RS2WC040 design is based on LSI MegaRAID
Entry* technology which offers the same robustness and many of the
same features as trusted LSI MegaRAID technology*. Configuration
options are simplified for entry-level usage models.

Seamless migration to more fully featured RAID

The Intel RAID Controller RS2WC040 shares common drivers with
enterprise-class Intel® RAID products which allows for simple
migration to more full-featured RAID-on-Chip (ROC)-based products
should system requirements change.
